franc! i just had the same exact issue right now, and i've been trying to fix it for 2 hours and you are the ONLY person on the internet with this error! :')
it took me so long to figure this out... the solution was to set:
"other linker flags" in build settings to
../../../addons/ofxKinect/libs/libusb-1.0/lib/osx/usb-1.0.a(posting it for people in the future coming across the same problem)
